HiI had a Problem with the HAL UART driver. On my Custom Board with STM32H7 the TX and RX Pin are connected together, so i have a local echo and read back everything i transmitt. My Problem now is that it will generate a Receive interrupt but don't f...
Hi ,all.I wanted to understand where the 16 in this equation comes from, cna anyone epxlain?
DocID025832 Rev 5In Table 13. STM32F042x pin definitions, "TSSPOP20" instead of "TSSOP20".JW
I use cubemx (6.0.0) to generate ADC1 configuration code, for example, ADC1 channels 1, 2, and 3 are injection channels, and TIM1 channel 4 is used to trigger, and ADC1’s 4, 5 are Regular channel. STM32F4 can work very well. But STM32G4 does not wor...
I am designing the application that uses both CAN interface and RTC. I noticed some weired behaviour that I need to fix somehow. Directly after upload the application starts and CAN working properly. With battery present (there is power on VBAT) if I...
Hello,I am trying to implement a low level I2C readbyte function, currently trying to read out register 0x41 (TEMP_H) and 0x42 (TEMP_L) from an MPU9250. The issue is that when I debug print the values, it seems that TEMP_H_Buffer appears to have the ...
HiI am trying to do a simple USART communication via DMA (LL Drivers). I want to send two chars to my STM32F103 from my PC which are received by DMA. In the DMA RX transfer complete callback I want to send some text string, also via DMA back to the s...
STM32 timers can decode quadrature signals.STM32 timers can count external pulses.can STM32 timers do pulse counting AND take counting direction from a second external input?my current solution (on an STM32F303CB/CC, but also F103) is to let the time...
Hi, I am also new to stm32 micro controllers. I am trying to use UART2 of my microcontroller which is not default(It is not connected with the ST-Link, hence no virtual COM PORT), I am using a USB to TTL connector(TX,RX and GND) for this, I am taking...
